Ollie Locke and Lionel Blair have become the final two CBB housemates to win immunity from the first eviction.

Today, housemates were given a final chance to unlock themselves from Big Brother’s shackles by solving Big Brother’s ropey puzzle.

They had to pass their key along a knotted rope to unlock their rope and then unlock their handcuffs.

As the first pair to unlock themselves with a time of 2.53, Ollie and Lionel escaped their shackles and won immunity from the first public vote.

As Lee Ryan and Casey Batchelor (2nd – 3.34) and Luisa Zissman and Evander Holyfield (3rd – 3.58) failed to unlock themselves first, they will now face the public vote along with Dappy and Liz Jones. These housemates will face the first eviction on Wednesday.
